I checked the owner's manual and the Liberty is definitely allowed 5000 pounds with the equalizer hitch and towing package. Mine came without the hitch, but I have the "tow/haul" button so I expect the towing package is there. I got my hitch at U-Haul, it bolted right in but isn't as pretty as one hidden behind the bumper.
My GVWR on the door sticker is 5600 pounds, and the weight on the registration is 4060. I've been to the dumps and had it weighed with /without trash in it, and it is 4000-something pounds, no doubt, so logically the GVWR on the door can only apply to the Jeep's load and tongue weight, or it could never be rated for even a 2000 pound trailer.
On the other note, the Lance trailers are real nice looking and apparently lightweight for their size. Are fiberglass exteriors and RV windows adequate to keep eastern black bears out? I've seen the trees scratched up in the woods I'm planning to stay in.
And, thanks for the answers, I'm not an insomniac, I work nights and this is my time off.
